To all whom it may concern:

Be it known that I, ELBRAHAM T. SHIP- IVAN, acitizen of the UnitedStates, residing at HoneyGrove, in the county of Fannin and State ofTexas, have invented new and useful improvements in Hand Cotton-PickingApparatus, of which the following is a Figure 1 is a view illustrativeof the manner in which my novel apparatus is carried by a workman.

Figure Qis a side elevation of the appas ratus with parts bIOkGIliLWtLY.

Figure 3 a top plan View of the apparatus.

Figure 4 isa longitudinal section of the apparatus.

Figure 5 is a section taken in the plane indicated by the line 55 ofFigure st.

Figure 6 is a section taken in the plane indicated by the line 66 ofFigurev 4.

Figures 7 and 8 are views of details hereinafter explicitly referred to.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings. i

Among other elements my apparatus includes a sack 1 to receive thepicked cotton.

The sack is provided with astrap 3, de-

signed to extend over the shoulder and breast of the workman after themanner illustrated in Figure 1. On thesack is a belt or strap 1 which isextended around the waist of the workman.

At 5 are attachments of the general configuration illustrated. :The sackl is open each side sufficiently to receive the wide ends of theattachments 5, and the wide ends of the attachments are connectetd byhooks 6 and eyelets 7 to the open portions of the sack and extend in theform of open tubes to the small ends through which the pickers operate.

As illustrated each picker ofmy apparatus includes a rectangular casing8 that is comparatively large at the end attached to the sack and isdiminished toward its oppoithesinall end of the picker is a p verhangingportion 8* which has for its function to prevent thepiclrer hooks,ereinafter described. from catching into the leaves of cotton plants.Extending across thellarge end of each picker casing 8 are shafts 10 and11 the ends of which are disposed in anti-friction bearings 12 car-'ried by the walls the casing 8. Garried by the said siaft isa sprocketwheel 13 on which v is mounted a picker chain 14 equipped with books 15,said hooks having for their function to engage and 1 move cotton fromthe bolls. A. third shaft 16 is also employed in combination with thepicker chain 1 1; said shaft 16 being disposed in the comparativelysmall end portion of the picker casing I and being mounted inanti-friction bearings and equipped with a sprocket Wheel 17. In thisconnection it is to be understood that a wheel on the shaft 11 at thelarge end of the casing is equipped with spikes 18 tiat serve to knockthe 'cotton from the hooks 15 intojthe sack.

through the wheels 10 and belt 10 For the purpose of actuating thepicker I employ a spiral spring 19 one end of which is connected at 20to the wall of the casing 8. The opposite end of said spring is stronglyconnectedto the shaft of the belt-carrying sprocket wheel and in this10" and the The shaft 11 is rotated from the shaft 10 connection it willbe understood that a pulley 22 on the same shaft carries a cord 23 oneend of which is fastened to the pulley and the other end to the beforementioned belt 4 From this it follows that when the picker is entendedthe spring 19 is placed under tension or compressed, and that theexpansion of said spring puts the picker in motion, whereupon the hooks15 will re- 1 move cotton from the bells, and the spikes 18 will removethe cotton from the hooks and cause the cotton to enter the sack. Someof the spikes 18 are arranged to work between the hooks 15 and others atopposite sides of the hooks 15. Manifestly the easings 8 are manipulatedthrough the medium of the handles 2 thereon.

The top walls 30 of the casings 8 are hinged and detachably fastened inclosed position through the medium of hooks 31 so that the interiors ofthe picker mechanisms may be conveniently inspected when occasiondemands.

It is within the purview of my invention to construct the several partsof the apparatus of any material or materials most appropriate to therespective purposes of the parts. I would state, however, that I preferin practice to construct the'casings 8 of aluminum.

It is also within the purview of the invention to fasten the sack to theattachments 5 so the attachments will hold the adjacent sack portionsopen for the passage of cotton into the sack, and to utilize the bottomwalls of the attachments 5 as doors.

Having described my inventiton, what I claim and desire to secure byLetters-Patent, is

1. A hand cotton-picking apparatus, comprising a sack, a picker casingthereon, a picker chain or belt, and spring actuating means; said meansbeing constructed and connected tobe put under tension by movement ofthe sack and picker casing with respect to the body of the person bywhom the apparatus is carried; the apparatus being provided with ahandle and with a strap to rest on the shoulder of an operator and abelt to pass around the body of the operator, and the spring means beingcon- ABRAHAM T.
